KRAFT KITCHENS TIPS
Prepare as directed, using 1 jar (15 oz.) chunky spaghetti sauce.
For perfect pasta that's cooked just right, test it often near the end of the cooking time suggested on the package. The perfect pasta is done when it's tender, but still slightly firm as you bite into it. To keep the pasta from cooking any further, immediately drain it in a colander.
